ABOUT
I'm an undergraduate student at the California Institute of Technology who studies quantum information, high energy physics, and the intersection of machine learning and science.
RESEARCH
- I'm currently developing error mitigation methods for quantum circuits at the Institute of Quantum Information and Matter at Caltech, using machine learning to create an intelligent compiler for noisy intermediate-scale quantum devices.
- I proposed and developed energy correction and clustering components in an end-to-end deep learning pipeline for neutrino experiments (DUNE and MicroBooNE) with the DeepLearnPhysics collaboration at Stanford, using semantic segmentation and graph neural networks.
- I demonstrated how deep learning can find particle tracks in the Large Hadron Collider at CERN under the HEP.Trkx project using graph neural networks.
- I proposed a new quantum machine learning algorithm for Higgs boson classification on the D-Wave quantum computer, as well as quantum annealing for particle tracking at the Large Hadron Collider.
- I simulated black hole collisions and implemented Bayesian methods for detecting the astrophysical gravitational wave background at LIGO.
- I developed genetic algorithm optimization for neutron imaging analysis of scintillating crystals at the Berkeley Space Sciences Lab, publishing our results in a peer-reviewed paper.
